To @Zlio/2,0m t may concern.' n i Be it known that I, MARKEY WEILER -SToU-FFER, a citizen of the United States, Vand a resident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Nonskid Appliances, of which the-following is a specification.

My invention relates to improvements in non-skid appliances for motor vehicle tires, and it consists in the constructions, combinations and arrangements herein described and claimed.

The foremost object of my invention is to provide a simple but effective non-skid device, applicable either to the pneumatic or solid type of motorvehicle tires, without in any way modifying or altering either the construction of the tire or the rim of the wheel.'l

A further object of the invention is to provide a simple, peripherally attachable tire armor. which can be put on or taken olf, with the same facility as the ordinaryv well known non-skid chain.

A further object of the invention is to provide an improved tire armor which can be easily strapped or otherwise fastened inl place around the tire and rim of the wheel, being left in place permanently if desired.

A further object of the invention is to provide an improved non-skid attachment for tires, embodying means for preventing lateral creeping on the tire.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of al wheel, illustrating the improved non-skid device v applied to the periphery of the tire,

Figure 2 is a plan view of a portion of the non-skid appliance. also illustrating means for making longitudinal adjustments to take up slack,

Figure 3 is a detail perspective view of a portion of the non-skid appliance, showing one of the attaching yokes with a companion corrugated tread plate.

Figure 4 is a detail cross section taken substantially on the line 4 4 of Figure 1,

`illustrating the mode of application of one of the yokes more clearly,-

Figure 5 is a detail perspective view illus.l trating the adjusting means between a pair of the plates, shown in Figure 2, and

Figure 6 isa detailsectional'view show-` ing the swivelconnectionv of'one ofthe vadjusting screws. A y n Generally `spealar1ng,-theinventlon 'come ties joiny aflinked tread belt 5. i Describing ,iirst, oneof the yyokes 1, this is seen in Figure 3 to consist of aI plurality of sections 6, suitably hinged together at.7 lto make the yoke adaptable-to slight variations in the -shape of the tire. y c

The innermost sections may either be perfectly straight as shown in Figure 4, or they may be slightly curved as desired. They are` provided with shoulders 8 which are usually close enough to theadjacent parts, as lfor example, the rim towhich the tire is attached,'.to abut these parts'andprevent lateral `motion of thetread 5 Awithrespect to the tire.l y

Connected' to the innermostextremities of rying the strap 10 off the fastening means 4, the othercarrying the buckle 11. The mode of fastening the yoke 1 to the wheel is not confined tothe strap and buckleconnections p y y v8o the sections 6 are links 9, one of which carshown in the drawings. Any desired fas- Running around the sides ofthe tire 3 and connecting all ofthe upper or outermost sections of the yokes 1 are cables 12. These. y

cables are threaded through holes 13 in the outermost sections vvas clearly shown in Figure 1. These. cables `are illustrated so that itmay be known that auiriliaryA fasteningf means can be employed.` y

Ordinarily itis notnecessary to'- use both the cables 12 andthe fasteningmeans 4, but

both can be used if desired. In caseonly the y cables 12: are employed, the innermost section 6 and fastening means 4 can be dis-4v,

pensed with entirely,the cables 12 then acting the same as the annular chains or cables of the well known types of anti-skid arrangements to hold the tread 5 in place.

Carried by,` each yoke 1 andr forming a part thereof, is ayoke tread plate 14` with surface lcorrugations vor serrations 15Eas clearly shown nFgure 3. Formed onthev 60 prises a plurality of yokes"1,pwhichion the y l Ainner extremities are secured beneath ythe rim or yfelly 2 of the tire 3 by any suitable l, fastening means 4, and on' the louter eXtrelni-v f to be understood mediate corrugated longitudinal extremities ci the yoke tread plate la are hinge lugs 16 to cooperate. with similar lugs 17 on the ends ot' the intertread plates 1S.

Hinge pins 19 lit through the various lugs when placed together in a manner obviously from the drawings, so that a flexible vtire tread results. This fiexible tread readily gives to the yielding of the tire and provides a very satisfactory antiskid shoe. Lateral lugs 20 receive hinge pins 2l, to which the outermost yoke sec tions (3 are connected.

lt will in many cases be necessary to effeet certain adjustments of the flexible antiskid tread in applying it to the tire. Such adjustments are made by the means shown in Figures2 and 5. A pair ot the intermediate plates 18 are provided with lugs 22, 23, the latter providing a swivel connection 24 for the adjusting screws 25. rlheee screws are threaded at the upper ends and occupy suitably threaded bores in the lugs 22.

Adjustn'ients are made by turning the heads 26 ot the adjusting screws, then lining the adjustment by means of the jam nuts 27. Dowel pins 28 on one of the halt tread plates, iit in suitable recesses 29 in the companion plate, so that the alinement ci the plates is not destroyed and the adjusting screws 25 are relieved of undue strains.

lVhile the construction and arrangement ot my Ianti-skid appliance as herein described and claimed, is'that oit a generally preferred form, obviously modiiications and changes may be made without departing ircm the spirit of the invention or the scope of the claims. f

l. An anti-skid tread, comprising a pair ci? attaching yokes consisting of sections hinged together, the innermost sectionshaving shoulders for abutting a rim, with suitable securing means reaching across the ends of said sections; a yoke tread plate with lugs to which the outermost sections are hinged, and intermediate tread plates hinged together and to the tread plates of said yokes.

- 2. An anti-skid tread, comprising. a plurality of plates hinged on end, certain ones of the plates having side lugs; a plurality of sections hinged together and to each of the lugs, and extending inwardly in respect to a tire,shoulders formed near the extremity ofeach inner section to abut an adjacent tire mounting and prevent creeping of the tread, links carried by said. sections, buckles carried by certain links, and straps carried by others, to reach beneath a telly and secure the tread on a tire.
